概要

Description

MP2208DL-LF-Z is a Monolithic Power Systems 2A step-down (buck) regulator. It integrates the high-side switch and current‑mode PWM controller in a small lead-free 8-pin package (DL) with RoHS (-Z) compliance. It uses an external inductor, diode (if not synchronous), output capacitor, and a feedback divider to set the output voltage. Key features typically include fixed switching frequency, enable/shutdown, soft-start, undervoltage lockout, and protections (overcurrent/overtemperature). It is suited for compact DC-DC converters to generate low-voltage rails (e.g., 3.3V, 5V) from higher Vin in applications like automotive, industrial, and consumer electronics. For exact electrical specs (Vin range, Vout range, switching frequency, current limit), refer to the MP2208DL-LF-Z datasheet and reference designs.

Features

Key features of MP2208DL-LF-Z (stepper motor driver)
- Two-phase microstepping motor driver with Step/Dir interface
- Wide operating supply: 4.75V to 36V
- Adjustable motor current via reference resistor (suitable for mid-high current motors)
- High-resolution microstepping for smooth motion
- Built-in current regulation with options for decay modes
- Protections: overcurrent, overtemperature, undervoltage lockout, short-circuit detection
- Sleep/Standby and Enable inputs; Fault/status indicators
- Low quiescent current in standby; high overall efficiency
- Compact LF-Z package, RoHS-compliant (surface-mount DFN style)
Note: For exact current ranges, decay mode options, and microstep levels, refer to the official datasheet.

Package

8-pin leadless DFN (QFN-8) package, 3x3 mm. RoHS-compliant lead-free (LF) variant.

Pinout

The MP2208DL-LF-Z is an 8-pin IC (plus an exposed thermal/ground pad). Typical pin functions are:
- VIN: supply input for the internal MOSFETs
- SW (LX/PHASE): switching node / output to the external inductor
- BST: bootstrap pin for the high‑side gate driver
- EN: enable / shutdown control
- FB: feedback input for output voltage regulation
- PGND (power ground): return for switching currents
- AGND or GND: analog/system ground reference
- NC or other auxiliary pin (depends on marking/version)
The exposed pad is the thermal/ground connection and must be soldered to PCB ground/thermal land per the datasheet. For exact pin numbering and any NC/AUX semantics consult the official MP2208DL datasheet.

Manufacturer

Manufacturer: Monolithic Power Systems (MPS).
What kind of company: MPS is a fabless semiconductor company that designs and sells power-management integrated circuits (DC‑DC converters, power modules, LED drivers, battery management, etc.) for computing, consumer, industrial, automotive and communications markets.

Application

MP2208DL-LF-Z is a high-efficiency step-down (buck) regulator. Typical applications: portable/battery-powered devices; embedded systems and MCU-based circuits; consumer electronics (set-top boxes, cameras, media players); automotive and industrial equipment needing local DC-DC conversion; networking/telecom gear; LED lighting drivers and other point-of-load regulators.
